Abstract

The energetics of three competing low-energy isomers of C-36 (D-6h, D-2d and C-2v forms) in their singlet and triplet states were computed at the AM1, HF/3-21G, HF/6-31G* and B3LYP/6-31G* levels. The most stable structure is predicted to be the D-6h isomer with a triplet ground state of (3)A(2u) symmetry. This electronic structure can account for the 'covalent' interactions noted in solid C-36. The dimeric structure with D-2h symmetry was optimized using the AM1 and HF/3-21G methods. Dimerization is calculated to be energetically favorable. Important changes expected due to dimerization in the vibrational and electronic spectra are pointed out.
